The Motorola G22 supports 4G bands 1/3/5/7/8/20/38/40/41, while T-Mobile USA uses bands 2/4/5/12/66/71. So, your phone is almost entirely incompatible with T-Mobile USA's 4G network, except in areas where BandΒ 5 is used.
You can check T-Mobile USA's device compatibility tools if you want, but it seems like the advice to purchase a phone with better US compatibility may be correct.
